HPCR/AA-250/SH-200 Fiber Optic Shutters

High Efficiency, Open and Enclosed Versions; Fiber Type SM, PM, RC; 780-1625 nm; Fiber Length 40-82 m; Fiber Stretch 3.8-8.0 µm/V; Fiber Leads 1 m, 0.9 mm OD Jacket; Connector Type Bare Fiber, FC/PC, FC/APC The PZ2 series provides the most extensive stretch of Optiphase’s stretcher product family. At the core of the PZ2 high-efficiency fiber stretchers is a fiber wound piezoelectric element for use in a wide range of optical interferometric measurement and sensing system applications. The PZ2 is ideal for use in OCT (Optical Coherence Tomography) and OCDR (Optical Coherence Domain Reflectometry) applications requiring scattering or boundary definition measurements. Optiphase’s expertise in the design, manufacture and use of all-fiber interferometers has produced a unique multi-layer winding approach resulting in an enhanced modulation function while maintaining a high operational frequency. PZ2 high-efficiency fiber stretchers are available with single mode (SM), commercial polarization maintaining (PM, Panda or Bowtie) or SM reduced cladding (RC) fiber types PZ2 high-efficiency fiber stretchers are available in two versions: Housed in an enclosure with connectors, making set-up and use quick and easy Bare lead fiber stretcher, not enclosed and including a convenient mounting kit consisting of a top-mount aluminum retainer and two silicone rubber pads - the mounting kit includes top or bottom mount Optiphase fiber stretchers are unique in that they do not require proprietary drivers. For most low-voltage applications (<±15 V) Optiphase stretchers can be driven by standard electronics such as signal generators, op-amps or other laboratory equipment without modification. For more information on how to drive PZ2 high-efficiency fiber stretchers see the downloadable application note.
